9 Water Detection Sensor Manufacturers in 2023
This section provides an overview for water detection sensors as well as their applications and principles. Also, please take a look at the list of 9 water detection sensor manufacturers and their company rankings.
What Is a Water Detection Sensor?
A water detection sensor is a sensor that uses long wavelength light absorbed by water molecules to detect water.
While general photoelectric sensors can detect and detect liquids, it is difficult to detect transparent water due to the extremely small attenuation of the light as it passes through it, and it is even more difficult to detect colored water or water with different color densities because the attenuation changes.
This water detection sensor uses light with a long wavelength that is absorbed by water molecules, making it possible to detect transparent water, colored water, and water with different color densities.
Uses of Water Detection Sensors
Unlike the liquid detection of general photoelectric sensors, water detection sensors use long-wavelength light that is absorbed by water molecules to detect water.
Also, because they can stably detect even atomized water, they are used in a variety of water detection applications, such as monitoring water washing by spraying at production sites and production environments where water is used, detecting the liquid level of water storage tanks and liquid level, and detecting whether transparent containers such as PET bottles and glass are filled with liquid. The principle of the water detection sensors is as follows.
Principle of Water Detection Sensors
General photoelectric sensors can detect and detect liquids even though light is reflected or diffused by water molecules, but it is difficult to detect transparent water due to the extremely small amount of light attenuation as well as light transmission. This makes detection even more difficult.
Water detection sensors, like photoelectric sensors, consist of a light emitting side and a light receiving side, and are characterized by the use of infrared light of 1.45um (1450nm) as the long wavelength light that is absorbed by water molecules.
By using this long-wavelength light absorbed by water molecules in the water detection sensors, water can be detected stably because the light is absorbed and blocked by water molecules even for transparent water, colored water, and water with different color densities. Because of this feature of the water detection sensors, when water is used for liquid components such as water droplets, bubbles, and bubbles with small bubbles accumulated, which are prone to malfunction with photoelectric sensors, water can also be detected stably because light is absorbed and blocked by water molecules in the same way.
